HUMIDIFYING-RADIATOR.

arplicmon filed February 25, 1915. Serial so. 10,424.

In my construction each radiator unit is provlded with a humidifyingchamber so dlsposed in relation to the heating conduits as to be withinthe lateral planes thereof, thus providing means whereby any number ofsuch units may be assembled to form the complete radiator according tothe require ments of the room, furthermore such a radiator has the sameappearance as the usual radiators used in steam heating systems and 1sequally accessible for cleaning. In my preferred construction I havealso provided means whereby the water chambers of the radiator may bereadily exposed for the purpose of filling the water chamber or forcleaning the same.

The drawings illustrate the preferred embodiments of the invention.

Figure 1 shows a radiator embodying my invention standing on the floorof the room and connected with means outside of the room for maintaininga constant supply of water in the evaporating chambers of the radiatorFig. 2 is a vertical sectionalview of one of the radiator units of thepreferred construction Fig. 3 is a horizontal sectional view on lines3-3 Fig. 2, Fig. 4 is a vertical sectional view of a modified form ofradiator construction, and Fig. 5 is a horizontal surface view on lines5-5, Fig. 4.

The radiator as illustrated in Figs. 1 and 2 of the accompanyingdrawings comprises a series of units or sections 1, each sectioncomprising parallel vertical conduits 2 for a heating fluid such assteam or hot water,

said conduits being connected at the bottom by a relatively largechamber 3 thus forming a U-shaped conduit. The several unitsareconnected at the bottom preferably by push nipples 5 and at the topby push nipples 6 thus providing for a constant circulation of fluidthrough the series of radiator sections. The heating be introduced atthe bottom of the radiator through the pipe 4 in the usual mannerpassing thence through the conduits 2 and the push nipples 5 and 6. Whenhot water isv used the same may be introduced through the pipe 4 at thetop of the radiator, passing thence through the push nipples 6, theconduits 2 and chamber 3, leaving through the usual discharge openingin. the manner usual-in hot water systems.

Each section is provided with a water fluid, if steam, may

chamber 2 within the loop formed by the vertical conduits 2 and thehorizontal connecting chamber 3, the sides of the water chamber t beingfiush with or within the lateral planes of the walls of the conduits 2.The walls of the conduits 2 and oil the water chamber 7 are desirablymade integral being connected by relatively thin webs 8 of such crosssection as to reduce the heat conducted from the heating conduits to thewater chamber suciently to. maintain the water in the chamber at adesired vaporizing temperature below the bog point of water. in someinstances especially where steam is used the heat conducting area of thewebs may be, still further reduced by cutting away the webs at intervalsto term slots 9 in which the air may circulate. By this means anyradiator of my construction may be adapted'tor the particular room inwhich it is to be located so that it will supply the amount of moisturenecessary to maintain the room at the desired degree of hidity.

"The water chambers of the radiator sections constructed in the manneraforesaid are connected by push nipples 10 m that all of the waterchambers of each radiator are connected together and a uni-form level orwater maintained throughout the entire radiator.

it is "sometimes desirable where a large number of radiators are usedupon a single floor to provide means for maintaining the water in thewater chambers at a constant level, such means may be easily. providedby the means illustrated in Fig; l which consists in a float tank Itlocated in an adjacent room or closet connected by a suitable pipe12.with an inlet pipe 13 leading to the first section of the waterchamber of the radiator. This pipe may be concealed beneath the floor ofthe room and provided with a riser lying adjacent to the riser of thesteam pipe which leads to the steam conducting sections of theradiator.-

In the preferred embodiment illustrated in Fig. 2 the heating conduitsare til-shaped, the upper end of each leg of the conduit being connectedthrough the nipple 6 of the adjacent radiator section. This leaves theupper ends of the water chambers open so that the same are accessiblefor cleaning by a brush or cloth. A suitable perforated cover 14 of therequired width and length maybe provided to inclose the top of theradiator thus constructed.

in order to make the radiator construction more hygienic the walls ofthe water chamher 7 may be provided with a coating 15 of porcelain,enamel or like substance.

In Fig. 4 l have illustrated a modified form of radiator which issubstantially identical in form with the usual radiator now in use. Inthis construction the radiator sections are composed of parallelvertical conduits 21 for heating fluid, connected at the bottom by achamber 23 and attheir top by an arch shaped conduit 2-l. The waterchamber 25 is, as disclosed in Fig. t, disposed within the lateralplanes of the walls of the heating conduitsand is provided at its topwith a relatively large opening 26 adapted to permit the treeevaporation of the water wit the water chamber. The lower portion orbottom of the water chamber may be made distinct from and separated fromthe outer wall of the chamber 23 to provide an air space 27 beneath thelower end of the water tank. The walls of the water tank and oil theconduit are preferably cast integral, the webs connecting the same beingrelatively thin and cut away to provide apertures or slots 28 by meansof which the radiating area of the web may be sciently reduced tomaintain the water at the desired temperature. lln this construction theseveral sections of the radiator are connected at the bottom by pushnipples entering apertures 29 at the bottom and similar push nipplesentering apertures 30 at the top. as in the usual radiator construction.llt is especially desirable to use means for maintaining a continuoussupply of water to the water chambers of radiators of this type sincethe water chambers are not so easily accessible as the type disclosed inFig. 2

and it is to be understood that such radiators may be connected to thefloat tank in the manner heretofore described.

With the radiator construction disclosed herein a relatively large bodyof water is maintained within the radiator sections and the heattransferred to the water chambers is proportional in each case to theamount of heat delivered to the room. By properly reducing the area ofthe webs connecting the water chambers with the walls of the steamconduits a nice adjustment may be made which. will cause approximatelythe desired amount of moisture to be supplied to the air at all times.

While l have described the water chamber of the radiator as beingconstructed preferably integral with the Walls of the conduit it is tobe understood that the water chamber may be made separate from theconduit 'and assembled within the same the walls of the conduit and ofthe water chamber being connected by a web of suitable conductingmaterial.

lit will be understood that the embodiment of the invention disclosedherein is illustrative merely and that it may be embodied in other formswithin the spirit and scope of the following claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

A radiator unit comprising a. conduit for a heating fluid and an openchamber adapted to contain a vaporizable fluid, the wall of said chamberbeing connected to the wall, of the conduit by arelatively thin web ofheat conducting material apertured to reduce the conducting area of saidweb sufficiently tomaintain the contents of said chamber at a desiredtemperature below the boiling temperature'of the liquid.
